Stage/gear simulator Function output control mode (Function switch setting 0, 4, 8 or C
depending on PPM output):
This mode is used to provide a stage/gear shift simulated output for boost controllers and other devices
that need to see a gear shift position switch output to change stages, such as:
· AMS-1000 boost controller from NLR Systems
· Innovative Turbo Systems MSBC01 Multi-Stage boost controller
Operation as MPH increases - When the 1 st table entry is reached the green wire “Activation” output
will turn on (provides a ground signal), starting Stage1 boost control. This output will remain ON until
MPH drops below 1 st table entry.
As MPH increases and becomes greater than or equal to next table entry the gray wire “Next Stage”
output will turn ON (provides ground signal) for .1 second then turns back OFF. This provides pulse to
increment the boost controller to the next stage. This process continues as MPH increases until the last
table entry is reached and/or a table entry is equal to 0.
As the MPH decreases the “Activation” output will remain ON until MPH is below 1 st table entry. Then
the “Activation” output turns OFF resetting the sequence (and in most systems, resetting your nitrous or
boost controller). If MPH increases the above sequence is performed again.
The settings for this mode are shown in Table A on page 6.
Vehicle speed switch Function control mode (Function switch settings 1, 2, 3 or 5, 6, 7 or 9, A, B
or D, E, F):
In this mode the STOV is a vehicle speed based switch, enabling and disabling the normally closed and
normally open switched outputs much like an RPM activated switch does based on engine speed.
For each PPM setting (2000, 4000, 8000 or 10,000), the STOV provides three different vehicle speed
range settings. The first mode provides a low speed range/high resolution signal of 0 to 15 mph in 1
mph increments. The other two modes provide a standard and high speed range mode in a coarser 10
mph increment (10 to 150 mph range and a 110 to 250 mph).
When vehicle speed exceeds the value set in Table B with the Function and Range switches, the
Normally Open (NO or OFF) activation wire connects to ground and the Normally Closed (NC or ON)
wire will open the ground path (was connected to ground before activation).
When the vehicle speed drops one MPH below the MPH set point, the process reverses itself and the
Normally Open (NO or OFF) activation wire will open the ground path and the Normally Closed (NC
or ON) wire will connect to ground (i.e. 1 MPH hysteresis).
The switch settings for this mode are shown in Table B on page 6.
